This document specifies the mechanical and physical properties of nuts, with coarse pitch thread and
fine pitch thread, made of corrosion-resistant stainless steels, when tested at the ambient temperature
range of 10 °C to 35 °C. It specifies property classes in relation to austenitic, martensitic, ferritic and
duplex (austenitic-ferritic) steel grades for nuts.
ISO 3506-6 provides general rules and additional technical information on suitable stainless steels and
their properties.
Nuts conforming to the requirements of this document are evaluated at the ambient temperature
specified in paragraph 1. It is possible that they do not retain the specified mechanical and physical
properties at elevated and/or lower temperatures.
NOTE 1 Fasteners conforming to the requirements of this document are used without restriction in
applications ranging from –20 °C to +150 °C; however, fasteners conforming to this document are also used for
applications outside this range down to –196 °C and up to +300 °C. For more details, see ISO 3506-6.
Outside the temperature range of –20 °C to +150 °C, it is the responsibility of the user to determine the
appropriate choice for a given application, in consultation with an experienced fastener metallurgist
and by taking into account e.g. stainless steel composition, duration of exposure at elevated or low
temperature, the effect of the temperature on the fastener mechanical properties and clamped parts,
and the corrosive service environment of the bolted joint.
NOTE 2 ISO 3506-53) is developed in order to assist in the selection of appropriate stainless steel grades and
property classes intended for use at temperatures up to +800 °C.
This document applies to nuts:
— with ISO metric thread in accordance with ISO 68-1,
— with diameter/pitch combinations in accordance with ISO 261 and ISO 262,
